@lwwntoz fitter/nu s 'JlIlIIIII-ll l mhwooeo and useful Improvements in Molding-Machines, of

operated machine that will effect in large part a very mold ofa casting. Broadly speaking, my invention OLIVER W.

KELLY,' OF SPRINGFIELD, OHIO.

MOLDING-MACHINE.

To all'wkomitmay concern:

Be it known that I, OLIVER W. KELLY, a citizen of the United States, residing at Springfield, is the county of Clark and State of Ohio, have invented certain. new

which the following is a specification.

My invention relates to improvements in molding machines, and particularly relates to a powenoperated molding machine such as to dispense with a vast amount of manual labor. Y e

The work to which I have applied this machine and one purpose for which it is particularly adapted is molding of piano plates, where owing to the light and heavy parts of the casting considerable skill is required in molding and ramming of the sand, and where, also, the

flask coht'aining the mold are exceedingly large and heavy and'the, wofk of handling the molds and flask when performed by manual labor is very great.

The objectof the invention is to construct a powerdesirable kind of rammingof the sand and dispense with the manual labor of ramming, and such that the arrangement permits the easy handling of the mold and flash containing the mold, requiring simply the proper operating of the machine to effect a complete utilizes a subvertible swinging frame to which the follow-board of the flask is supported and the arrangement is such that the follow-board and-flask can be vibrated by power in a manner to accomplish the properramming for heavy and light backing of sand, and I have shown a complete machine so arranged that the sand is conveyed by power to the flask, the sand rammed by power and the follow-board automatically released from the swinging frame when it is in normal position and automatically fastened to the frame in all other positions.

In the drawings, Figure l is a side view of the cornplete mechanism showing the conveyer and the molding machine in their associated positions. Fig. 2 is a sectional view taken on the lines A A Fig. 6. Fig. 3 is a sectional view taken on the lines B B Fig. 6. Fig. is a side view of the molding machine. Fig. 6 is a plan view of the molding machine. Figs. 5, 7 and 8 are detail views of the parts thereof. Fig. 9 is a modification showing the vibrating mechanism for largesiz'ed machines- Fig. 10 shows a detail of the tapered guides.

Like letters of reference indicate like parts throughout the several views.

In my machine, the stationary frame for the molding machine is indicated by a (Figs. 1 and. 6). There is supported upon the stationary frame a driven shaft, a andthe main operating shaft is indicaied by a (Fig. 6). A pulley, a is shown for applying power to Specification of Letters Patent.

a near the center thereof a gear wheel, a and there is splin'ed'to the shaft near the'gear wheel a sleeve a.

The gear and sleeve are provided with clutch faces, as

these beveled gears are journaled loosely on the shaft a A friction clutch, a, is splined to the shaft, a

and the posit-ion of this clutch is controlled by the hand I lever, a. (Figs. 3 and 6). The shaft, a is journaled loosely within stationary bearings, a, near eaclr end thereof (see Figs. 4 and 6) and secured rigidly to the end of the shaft, a is a worm, a. The hand lever,

a", is pivoted to a support, a, projecting from the sta- Y tionary frame, a (see Fig. 3); the hand lever being that whenever the hand lever, a", is operated, the

clutch, a", may be shifted from a position of engagement with one bcveled'gear, a to one engaging the other beveled gear, a", or vice versa. is shown in mesh with a gear, a", whicltgear is journaled securely to one end ofthe saidshaft, a .(Fig. 6). This shaft, a, is journalcd loosely in the stationary frame, a a, and there projects from the shaft, at, arms, b, (Figs. 6 and 1) which are securely fastened to it. Consequently, whenever the shaft, 21 is rotated, the arm, b, swings therewith. These arms, b b, with It is obvious The worm, al

the connecting rod, b constitute the swinging frame to -which is secured the flask and follow-board, as will be more fully explained hereafter.

It is obvious from the description thus far given that power applied through the main operating shaft, (1 to the beveled gear, a a, will raise and lower the swing-' ing frame, I) b, depending upon whether the friction clutch is in engagement with the one beveled gear or the other.

I have shown in Fig. 6 the friction clutch, ahin intermediate position such that the swinging frame remains stationary in its lowermost position (the position shown in Figs. 2 and 3) until the hand lever, a, is operatedtothrow the friction clutch into engaging "I have referred to the gear, (1*, on the main operating shaft 0 and adapted to be driven by the clutch sleeve, a, and this gear is shown in mesh (Fig. 6) with the gear, a, secured to the intermediate shaft, a so that motion is transmitted from the main operating shaft,-a to the intermediate shaft, a. This shaft, a, is loosely journaled in the main frame a a of the machine and carries at either end thereof knockers, a, which operate as means for vibrating the flask, as will be shown.

It is readily seen that the shifter, a, is shown in a po- I sition (Fig. 6) such that the clutch sleevegofi pnd knockers, a cooperate with friction rollers, a, pivoted to arms, a, (Fig. 2) which arms project from the follow-boa'rdgas hereinafter. explained. I have also shown anviLp'lates, a, and buffers, a, which also project from-thefollow-board and cooperate with the anvil-plates to cause the ramming of the sand. There is shown guides, a, which project upwardly from the frame, a, of the mach'ines,-and these guides cooperate the proper ramming of the sand.

with supporting projections, a, which project from the jolting frame, a and thereby the follow-board-is guided in its vibratory movement. This follow-board ;is indicated by a, (Figs. 2 and 3)'and normally rests upon said jolting frame, a. In 2 Theme shown this follow-board and jolting frame elevated from the swinging framein the act of being vibratedup and down for the purpose of ramming the sand. It is also to be noted that I have preferably shown two knockers at each end of the shaft, (1 (Figs. 2 and (i) so that the followboard and flask are vibrated twice at each cornplete revolution of the shaft.

In Fig. i) I have shown a slight modification such that the main operating shaft, a, is shown intermediate of two shafts, a, and each shaft, a", carries two separate knockers and there are corresponding supporting arms, a, projecting from thefollow-board cooperating with these knockers to give a large-sized flask and follow-board sufficient vibratory motion to accomplish I have shown a pin, a, on each sidc of the follow-board, ri (Fig. i) whi h acts as'a guide for the flask, and l have shown pins, at", at each end of the swinging frame which act as guides for the follow-board a.

The arms, I) b, are connected together at their free ends by the rod, b, (Figs. 6 and 2)and on this swinging frame the follow-board, a", is first placed and same is automaticaliy locked to the frame as will be explained hereinafter, whenever the frame begins to swing upwardly; The flask, 5-, is placed upon the follow-board,

,i nstrun1entality of the pivoted pawl, d", and its associated parts shown in l igs. 5, l and 6.

This pawl; b, is pivoted at If to one arm, I), of the swinging frame, and there are corresponding locking parts at each side of the frame. When the frame is in its lowermost position the tail of the pawl; it. strikes the pin, b, secured to the main stationary frame;

The follow-board, a', has a perforated flange projecting therefrom indicated by b, and the arm, 7:, has a perforated flange, 6 A pin, b slides within the perforations of the flanges and is spring-pressed into such position that the follow-board is locked to the swinging frame, but when the pin, b",'-throws the pawl, I), such that the upper end of the pawl strikes the head, I)", of

the pin, 'b the pin, 1), will he slid to the right (looking at Fig. 5) against the tension of the spring, b hand the follow-board will thereby be released from locking position with the frame, but it is apparent that when the frame,-b, swings upwardly and the, pawl, b, swings away from the stationary pin, b, the spring, I), will automatically slide thepin, b into locking position;

of a rope, c, which is secured to the rod, b."& .il1ave" and the sand automatically fedand discharged into the movable hopper, c, which can be shifted from front to rear so as to feed the sand in the proper places in the flask, 12 It is apparent from the fact that the gravity weight, 0, is connected with'the movable hopper, c, and also with the flask, that when the flask is overturned the gravity or counterweight, c, will drop. and simultaneously move the movable hoppcr, c, iipwardly' thereby moving the same from the path of movement of the flask, and when the movable flask restored to normal position the movable hopper, c, vwill be auiomat ically thron n back to normal position shown in Fig. 1. I

flaring explained the different parts, a brief dcscrip; tion of the operation is this: Power is applied in any ordinary way to the machine, and aftcr the sand has been partly fed into the iiaslgor if desirable during the major part. of the time it is being fed into the flask. the follow-board, 11', is vibrated by shifting the hand lcvcr, a, so that the clutch sleeve, o ,and gear, a", will be thrown into engagcn'icnts The knockers, a will thereupon accomplish a very desirable ramming of the sand. When sufficient ramming has been done, ihe

shifter, a, is again operated to disengage the clutch and the top of the flaskis thereupon secured to said flask and the hand lover, a, is operated to swing the sub-. vertible frame, it being understood that the flask has been clamped to the follow-board, the follow-board being automatically locked to the swinging frame at the commencementof the swinging movement thereof. The frame is swung until it is completely overturned upon a stationary support, such as that indicated in Fig. l by 0". The flask is then disengaged from the follow-hoard and the hand-lever, a, is again operated to I throw the clutch, a, to its opposite extreme position for the purpose of returning the swinging frame to normal position. In this manncr'the flask is deposited at a point in proiiimity to the machine, and the swinging frame is returned to normal position ready for another operation. in the initial. return movcm ent of the swinging frame, the follow board, to whichis secured the pattern, will be raised substantially vertically, thereby removing the pattern from the flask without disturbing the mold. This ispermitted by reason ofthe tapered guide pins, a.
